Why We Cannot Create a Generic Array in Java ?
Java does not allow creation of array with generics as elements.
In Java an array has to know the type information of its elements at runtime.
This information is used at runtime to throw ArrayStoreException if data type of an element to be inserted does not match the type of Array.
In case of Generics, the type information of a collection is erased at runtime by Type Erasure. Due to this array cannot use generics as elements.
